Using static Day value in a particular Date

Hi ..

Have a requirement in which I have to search particular day for the current month , the query is running .. For ex . If I am running query for May'2013 the where condition should be resolved to ( where date = 05/11/2013 ) ( Where 11 is the static value )

I tried this using below option , wanted to know if there is any better way of doing this , as I have to use couple of values using IN clause , For ex. ( where date in 05/11/2013 , 05/15/2013 , 06/11/2013 )
